well today we had our first turkey egg hatch........

how long do we leave him/her in the incubator (its a joint hatcher/bator). i've read differing oppinions.
also how long before they have their first feed..... it hatched at 3pm so still a bit damp
we've sorted heat lamp etc ready for their first move.......
also how long do we wait before getting rid of the other eggs, (that may not be fertile/viable)
